    • A method for forming an image in a silver halide color photographic light-sensitive material comprising developing an imagewise exposed silver halide color photographic light-sensitive material and then bleach fixing the silver halide color photographic light-sensitive material in a bleach fixing bath, the silver halide photographic color light sensitive material comprising a support having thereon a silver halide emulsion layer containing a yellow coupler, a silver halide emulsion layer containing a magenta coupler and a silver halide emulsion layer containing a cyan layer, wherein the silver halide emulsion layer containing the magneta coupler contains at least one kind of pyrazoloazole type coupler represented by the general formula (I): ##STR1## wherein R.sup.1 represents a hydrogen atom or a substituent; X represents a hydrogen atom or a group capable of being released upon a coupling reaction with an oxidation product of an aromatic primary amine developing agent; Za, Zb and Zc each represents a methine group, a substituted methine group, .dbd.N-- or --NH--, one of the Za-Zb bond and the Zb-Zc bond being a double bond and the other being a single bond; an aromatic ring may be condensed to the Zb-Zc bond; R.sup.1 or X may form a polymer including a dimer or more; and when Za, Zb or Zc is a substituted methine group, the substituted methine group may form a polymer including a dimer or more; a photographic layer of the silver halide color photographic light-sensitive material or a processing solution contains at least 5.8.times.10.sup.-4 mol per mol of silver halide contained in the silver halide color photographic light-sensitive material of at least one compound represented by the formulae (I) or (II): ##STR2## wherein R.sup.2, R.sup.3, R.sup.4 and R.sup.5, which may be the same or different, each represents a hydrogen atom, a hydroxy group, an aliphatic residue, an alkyl group substituted with an aromatic group, an alkyl group substituted with an alkoxy group, an alkyl group substituted with a hydroxy group, a carboxy group or an alkoxy carbonyl group or an aromatic residue; or R.sup.2 and R.sup.3 may be bonded each other to form a 5-membered or 6-membered saturated or unsaturated ring; and a developing agent which is introduced into the bleach-fixing bath is at least 1.0.times.10.sup.-4 mol per mol of a bleaching agent thereof.

    • A color photographic light-sensitive material comprising a support having thereon, in sequence:(1) a blue-sensitive silver halide emulsion layer containing, dispersed in the emulsion using a high-boiling organic solvent, a yellow coupler represented by the following general formula (I): ##STR1## with the weight ratio of the high-boiling organic solvent for dispensing the coupler to the yellow coupler being 1.0:1 or less;(2) a green-sensitive silver halide emulsion layer containing a magenta coupler represented by the following general formula (II): ##STR2## (3) a red-sensitive silver halide emulsion layer containing a cyan coupler represented by the following general formula (III): ##STR3## (4) an ultraviolet light absorbing layer containing an ultraviolet light absorbent represented by the following general formula (IV): ##STR4## in which the substituents X, Z, and R.sub.1 -R.sub.12 are as defined in the specification. The color photographic light-sensitive material provides a dye image which is resistant to fading or discoloration by light, and in particular provides color prints having a well-balanced fading of the dye image composed of the three yellow, magenta and cyan colors.
